Analog Devices LTC3886 | Demoboard DC2277A

Description

Demonstration circuit 2277A contains the circuitry neededto program and verify the EEPROM of the LTC®3886 in theUKG package and that is its only purpose. The DC2277Ais shipped with a LTC3886 installed in the clamshell styleprogramming socket and its EEPROM contains the factorydefault configuration. The LTpowerPlay™ #.proj file thatcorresponds to the factory default can be found inthe GUI.In order to properly verify the contents of the EEPROM,download and install the LTpowerPlay software (GUI).The software can be downloaded from:http://www.linear.com/ltpowerplay
